' :Beit known that 1, ANDREW W. REDIN, a citizen of the United States, residing at ho clgford, in the-county of Winnebago and State of. Illinois, have invented certain'new -and; useful Improvements in Mechanical .ldovements, of which the following is a specification-.:-; y I The object of this invention is the producw'tion of an improved mechanism for alternately imparting. rotary and oscillatory movements'to a member. .I have herein. shown my invention as employed to produce the rotary and oscillatory movements required in the operation of a circular g hosiery. knitting mechanism, although it will be understood that the invention isnot limited to such use.

14. The bevel pinion 14 is in mesh with a bevel pinion 16 rigidly mounted u on'the' lower end of the vertical shaft 7. ixed to the shaft 10 at one side of the gear wheel 12 is a clutch ,arm 17 adapted by means to be hereinafter described to engage said gear wheelan'd continuously rotate it in one'direction. At the opposite side of said gear wheel is a clutch arm 18 also adapted to en-- clutch arm being given a continuous oscillatory movement by means tobe presently described. The clutch arms 17 and 18 are alternately connected with the gear wheel 12' in order at certain times to rotate said gear 7;)

wheel continuously in one direction and at other times to give said gear wheel an oscillatory movement.

' In the present embodiment the clutch arm 18 is driven from the gear Wheel 9 by means comprising an arm 19 rigidly fixed to a rock shaft 20 mounted in the machine frame. Preferably the weight of the arm 19 and its connections is counterbalanced by a torsion spring 2 1 connected at one end with the shaft 20 and at its other end with the frame 1.- The outer end of the arm 19 is connected with a wrist pin 22 upon one face of the gear wheel 9 by means of the connecting rod 23 and with the crank arm 18 by means of the connecting rod 23. The are of movement of the crank arm 18 is preferably made adjustable by any suitable means, as, for example, by adjustably connecting the arm 19 and the connecting rod 24-, which may be done by slidably mounting the pivot pin 25 in an elongated opening 26 in the outer end of the arm.

4 The means carried by each of the clutch arms 17 and 18 for connecting them with the gear wheel 12 being identical, a descriptionof one will suffice to impart an understanding of both. Said means consists, in this instance, of a clutch pin 27 slidably mounted in the outer end of the clutch arm to move transversely thereof. One end of said'pin-is adapted to enter an opening 28 in the gear wheel 12, and between theother end of said pin and a fixed part of the clutch arm is a coiled spring 29 tending to move the clutch pin into engagement with said gear wheel.

At a point between its ends a locking shoulder 30 isformed upon the clutch in and a locking plunger 31 is adapted to -'e behind ..-sfiidnheulder'for lockingthe pin out of en- 1 gagemen? with the gear wheel 12. A spring 32 tends to move the locking plunger 31 into locilring engagement with the clutch pin 27. (Lugs 33 and 34 upon the outer ends of the 5 clutch pin 27 and the locking plunger 31, re, spectively, are provided for engagement by inclined cam faces 44 and 45 adapted to en-' gage the lugs 33 and 34 on the clutch pin 27 and the locking plunger 31, and withdraw said locking lunger from engagement with said clutch pin and said clutch pin from engagement With-the gear wheel 12. It will thus be seen that when the bar 35 is moved to the left from the position shown in Fig. 3, the pin 39 will be moved into position to engage the clutch pin 27 carried by the clutch arm 18 and thereby disconnect said clutch arm from the gear wheel 12, and that the pin 40 will be moved into position to engage the locking lunger 31 carried by the clutch arm 18 and t ereby connect said clutch arm with said gear wheel. A movement in the opposite direction (into the position shown in said figure) will disconnect the clutch arm 18 from the gear wheel 12 and connect the the supporting frame.

clutch arm 17 therewith.

Any suitable means may be employed for reciprocating the bar 35. I have herein shown said bar as reciprocated by means of cams 46 formed in and upon the peripl'ieral portions of a ratchet wheel 47 and engaging roller studs 48 on the bar 35. The ratchet wheel 47 is carried by a shaft 49 mounted in Said ratchet wheel is rotated through any suitable connections, as, for example, by means of a pawl 50 pivotally mbunted upon one arm of a lever 51, said lever being carried by a shaft 52. The other arm of the lever 51 is )ivotally connected with one end of a rod 53 slidably mounted in a bearing 54 in the framework 1. Upon the other end of said rod is a roller stud 55 ada ted to be engaged by a cam 56 fixed upon t e gear wheel 9. The rearward or restoring movement of the pawl 50 is herein shown as produced by a sprin 57 fixed at one end to the rod 53 and at its other end to a stationary part of the machine frame. A stop pin 58 carried by the rod 53 limits the s rmg-actuated movement of said rod by striking against the bearing 54.

When the mechanical movement herein shown is employed in a circular knitting machine, means may be provided for suitably controlling the movements of the ratchet wheel 47 in order-to effect ashifting ofethe clutch connections before described at the proper times to form the different parts of the stocking. In the present embodiment, said paw 50 to prevent engagement of said awl with the teeth of the ratchet wheel 47.

per side of the detent. Suitab e mechanism (not herem shown) is provided for moving the detent 59 into and out of operative relation with the pawl 50.

1 In operation, the gear Wheel 9 andthe clutch arms 17 and 18 move past said pins without being affected thereby. Then the bar 35 is proved longitudinally to the left, the clutch pins 39 and 40 are shifted in osition so that. upon the next movement of t 1e arms 17and 18 past said clutch pins, the pin 39 will disengage the clutch arm 17 from the driven Wheel.

12 and the clutch pin 40 will withdraw the locking plunger 31 carried by the clutch arm 18 and thus permit said clutch arm '18 to engage the driven wheel 12. The exehange of connections just described takes place as the clutch arms 17 and 13 swing downward sideby side.

It is evident that various changes may be made in the embodiment. herein shown without departing from the spirit and-scope of my invention, therefore no undue limitation en so inserted the pawl 50 slides idlv up on the upcontrolling means comprises a cdetent 59 1 adapted to be inserted below the point of the should be understood from the foregoing detailed description.
